"We know most of the aliens' tricks by now, even if Alien Resurrection gives them the chance to chase human prey through garbage-strewn waters and swish their tails like marauding raptors. They still invade human hosts and burst out horribly at inconvenient moments; they still enjoy some of the most stomach-turning breeding habits imaginable. The new wrinkle this time is that neo-Ripley finds herself strangely sympatico with these creatures, even to the point of experiencing maternal stirrings late in the story. A new queen alien has appropriated some of Ripley's re-productive system and can now produce live, skeletal, screeching, glop-covered offspring. Maybe that tells you more than you want to know."
